2 Claims.

The primary object of the invention is to provide pivotal mounting means which may be used in the support and mounting of any member where it is desired to have a mounting affording pivotal movement of such member between two positions, such as a folding washstand or the like.

Another object of the invention lies in the provision of pivotal mounting means having two points of pivotal movement in which the pivot points are shiftable in tracks to provide full pivotal movement.

A further object of the invention is to provide pivotal mounting means having two points oi `pivotal movement shiftable in tracks wherein means are provided for separation of the pivotal member from the track.

Other and more specific objects of the invention will become apparent from the following description read in conjunction with the accompanying drawings, in which- Fig. l is an enlarged front elevational view of a folding washstand in closed position and incorporating pivotal mounting means as used in the present invention;

Fig. 2 is a sectional view taken on the line 2 2 of Fig. l through the folding washstand showing the relative interlocking positions of the pivotal mounting parts;

Fig. 3 is a central vertical sectional view through the folding washstand in fully closed position and having parts broken away better to reveal the operation of the pivotal mounting arrangement and showing in broken lines how the washstand may be removed from the mounting means in an intermediate open position of the stand;

Fig. 4 is a detail perspective View to larger scale of the supporting track bracket for the folding washstand which is iixedly mounted inthe washstand recess in use; and

Fig. 5 is an enlarged fragmentary detail view of the pivotal mounting arrangement for the washstand showing the relation of the parts in the fully open position of the washstand and in that intermediate open position where the pivotal point for-the opening movement changes from the lower trunnion to the upper trunnion.

In the drawings, a supporting washstand 24 is housed in a cabinet 25 wherein it is hingedly mounted for pivotal movement between a vertical closed position and a horizontal operative position. The folding washstand is hinged in the cabinet 25 and comprises a basin |9| enclosed by and carried in the housing 24 which conforms to the surface contour of the cabinet 25 into which it is received when folded. The washstand is operated by means of a handhold 34 and empties, automatically, into a drain |92 leading beneath 'the car as the washstand is closed after use. Stationary pipes |99 and faucets |89 supply hot and cold water in the usual manner.

The washstand 24 as shown in Fig. 1 is made narrower at its lower portion as at 14 to accommodate pivot brackets |15 on the washstand and track brackets |16 in the respective side walls of the washstand recess |18 and the space between this narrowed portion and the side walls of the recess is covered by fixed flanges |11 flush with the face of the washstand and forming part of the cabinet housing the washstand but which might form part of any surface in which it is desired to mount the washstand. The flanges |11 serve to conceal the pivot mounting brackets |15 and |16, for the washstand, from view.

The washstand 24 is supported at each side in "the brackets |15 and |16 and is pivotally movable therein from the fully closed vertical position shown in Fig. 3 to the open horizontal position for use indicated in Fig. 5 and without leaving an opening between the rear edge of the washstand and the back wall of the recess |18. The track brackets |16 are xedly secured upon the respective side walls of the washstand recess by fastening means set in liush with the surface of the brackets and are so disposed as co-operatively to be engaged by the pivot brackets |15 on the washstand, thereby to support the washstand for the required pivotal movement. The brackets |165Y are, each of them, provided with a pair of coplanar converging tracks |19 and |88 each of which is developed in the form of an arc generated about a radius point within the limits of the other track end, as shown, is actually swung on an arc from the terminus of the respectively opposite leg. The tracks |19 and |88 on the "respective brackets |16 are disposed over and most extremity |84, thereof.

' washstand the trunnion |82 is disposed in the lower track |80 at the outermost extremity or terminus, thereof, |83 and the trunnion 8| is disposed in the upper track |19 at'the inner When it is desired to open the washstand for use, the user grasps the handle 34 to pull the washbasin out of the recess |18, whereupon the trunnion |82 acts as the initial pivot point in terminus |83 of the lower track while the trunnion |8| traverses the full length of the upper track and when this Vlatter trunnion reaches its nal position of ing or space between the rear of the wash'basin f and the recess |18. Y

The washstand assembly including brackets |15 may be installed inthe recess |13 in the fixed brackets |16 without removing any of the attaching screws for either of the brackets. Both the upper and the lower tracks |19 and |80 in each of the brackets |16 are each provided with an opening |85 and |31, respectively, for the placement and removal of the washstand. In Fig. 3 the washstand 24 is indicated in broken lines as it is inserted into the recess. It is necessary in this operation to insert the narrowed lower end of the washstand into the recess |18 in such manner that the trunnions |8| and |82, on the respectively opposite sides thereof, will pass over the flange |11 at each side of the recess after which the trunnions |82 must be passed in front of the upper tracks |19 and inserted into the openings |81 in the lower tracks while the trunnions |3| are being worked into the openings |36 in the upper tracks after which the washstand may be operated between'its extreme positions. The washstand may be removed in this same manner in reverse sequence.

Faucet assembly |89 connected by means of pipes lS with sources of hot and cold Water supply affords means for iilling the basin |9| with water for washing, and which is emptied into the drain |92 as the basin is closed, to be discharged through suitable outlets (not shown) onto the right-of-Way. Resilient stop |93, as best shown in Fig. 5, limits the opening movementof the washstand and relieves the brackets |15 and |16 of a portion of the load imposed in this position.

From the foregoing it will be seen that a two point pivot arrangement for the mounting of any member in pivotal relation to another has been provided in which pivotal and sliding movements have been combined to reduce the amount of space involved in the operation of the pivotal member and wherein such member may be dismounted from the other without the necessity of disassembling the pivotal mounting members.`

What is claimed is:

1. A basin adapted to pivot through substantially ninety degrees from a vertical inoperative position to a horizontal operative position, a vertical support for the basin including a recess opten on a side of the support and having a height and width slightly greater than the corresponding dimensions of the basin and a depth "greater than the thickness of the basin and adapted to receive the basin in such manner that t the `sides ci the basin are disposed closely adjacent to the sides of the recess and the bottom t form of an arc generated about a pointwithin the limits of the other track and disposed adjacent to one end thereof, one of said pairs being mounted on the support at the respective sides of said recess in xed relation thereto, the lugs being adapted to iit into the track members and cooperating therewith to support the basin in such manner that the basin during the iirst part of its movement from vertical inoperative position toward horizontal operative position rotates about a substantially fixed axis so that the basin clears the back of the recess, and during the remainder of its movement toward horizontal operative position is moved linearly toward the back of the recess so that when in its operative position the basin projects a minimum distance beyond the frontV of the support, the lugs during said movement of the basin moving linearly in their respective tracks, the other of said pairs being secured to the basin in xed relation thereto, and means whereby the lugs and tracks may be separated to remove the basin from the support Without disturbing the fixed relation of either, the tracks having means associated therewith for fixing the basin withv resect to horizontal motion relative to the support.

2. A basin adapted to pivot through substantially ninety degrees from a vertical inoperative position to a horizontal operative position, a vertical support for the basin including a recess open on a side of the support and having a height and width slightly greater than the corresponding dimensions of the basin and a depth greater than the thickness of the basin and adapted to receive the basin in such manner that the sides of the basin are disposed closely adjacent to the sides of the recess and the bottom of the basin is substantially aligned with the front of' the recess When the basin is in inoperative position, means at each side of the basin for pivotally mounting the basin in the recess including a pair of lugs and a pair of bearing members, the lugs on each side of the basin being spaced apart at a xed distance equal to the distance between the corresponding bearing members, one of said pairs being mounted on the support at the respective sides of said recess in xed relationY thereto, one of the bearing members of eachpair being disposed adjacent to the rear of the basin, the other bearing member of' each pair being disposed at an intermediate position with respect to the basin, the lugs being adapted to t into the bearing members and cooperating therewithto support i the basin, the basin when in vertical 'inoperamembers during the initial movement of the basin toward operative position, the basin during the remainder of its movement toward operative position being adapted to'pivot about the intermediate bearings so that when in its operative position the basin projects Va. minimum distance beyondthe front of thesupport, Vthe otherV of said pairs being secured to the basin in xed relation thereto, means whereby the lugs and bearings may be separated to remove the basin Vfrom the support without disturbing the fixed relation of either, and means for limiting the pivoting movement of the basin to the position corresponding Vto horizontal operative posiion.
